Lamps of this type are usually ventilated through a hole punched nit-he lul or cover.

'l`he partiiznlur pnrpoe ol' in'v invention is to provide a eoi'ietrut'tion arrangement ot tithe wliith obviates illtN t|ll`lttl.l\)ll y liowii. the tube itl isilispowil between the upper rear poi-tion ot the lanip body and tht` upper end ol' the shunt; ot the hook. itsv lower entl :soldered to and eoiinnunitat'ing with the iiiteiioi oi: the. hotly. a at lOl". while it\l upper t-ntl ttl" extends well above i ol lered or other- \\i.t` stviii'eil to the hooli. by which it'` forms a lnaee between the liiinp and hook to stav and ti-engthen the. latter. 'lhe portion or the tithe hetween'the hotly and hook is provided with an ott'set oieroolt', preferably in the forniol a eo'il or worin il. eonetitutii'ig :in ohSti'ut-liug nieniher, elementv or trap in the line ot' the tube.

ity the tleseribed arrangement oll the tube, it will lie obtrved that Said tube isrtlisptmeil at the highest. and rearinosti portion eonsidt-rations. the inineiI inay ineline his: head toi-ward to a greater degree with less liability ol eausing eeeape 'o't oil through tlie tube than il the tube were arranged t'ar'ther lorward` a5 in constructions Coininonly in nee. ln addition, the otliset, coil, worin. trap., oi' obntruetnig device l1 retains l and prevents the estupe ot? any oil which or a. ventilation tube extending therethrough. i

rlhis hole or tube is thus arranged far venough forward to pei-init of the escape of oil when the niiner stoops or assumes other than un erectposition, or suddenly moves;

his h'ofl or head. As a. result a vaste ot' ing a supporting hoot:

may, through any violentl motion of the initier, tintl ite way into the tube, so that; it; will run butfli into the lamp and wastel loe thus I'irevented. s this passage of oil into the tube will Seldon'i oeeur and as the Coil hiloes notohstruet the tube againstv the free inlet of an' and exit'of gases, thorough anti etlfeetive ventilation ol' the lanip ie insured and liability ot oxploeion prevented. rlhe strength and durability ole the lamp is also increased by reason of the tact that the tube tortue a brace between the lainp and :iupn porting hook.
